Problem when switching between xscope and other apps

Whenever I leave xscope to go to another app, sometimes calls, or texts, or the news app and then return to xscope to continue what i was reading or by opening a new link, all of my tabs I had previously had open and loaded have to load all over again.

Why does this happen? it happens regardless of how I leave xscope (back button, home button, home long press for recent apps, etc) and when I return with 5 or 6 tabs open it slows down the one im currently viewing significantly.

I would think if I have opened a page in the browser and it has loaded completely... and go to my home screen for a quick check of say my inbox, and then return to xscope... my page should be just how I had left it...

Is this a common function of this browser, an adjustable setting that seems to have eluded me, or perhaps an uncommon problem?

Happens to me all the time, and I assume to others. Or maybe other people don't browse this way? Basically, it's Android's supposedly advanced memory management killing the process once it's backgrounded.

Yes.
Some how it gets worse on Froyo based on my limited experience.
Android reclaims memory occupied by apps if they are not visible. On pre-froyo, it will not do so unless the memory is really low. With froyo, it gets very aggressive and kills background apps with no mercy. When apps are brought to foreground again, they have load from so called Bundle (not from internet???)
